Wireless Firmware Engineer (Direct To Cell)

SpaceX • Sunnyvale, CA

70d • $130,000 - $180,000

About The Position

SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars. The direct-to-cell program is working to provide global cellular connectivity from space. As a wireless firmware engineer, you will play a critical role in developing novel wireless signal processing algorithms, implementing optimized software for use on satellites and ground stations, debugging complex systems and performance issues, and developing production software. This is a unique position which will work closely with both wireless systems engineers and protocol firmware engineers to accelerate wireless PHY development and find solutions to interdisciplinary challenges. The ideal candidate will be equally comfortable with wireless signal processing algorithms and high-performance software development.
